+/*!
+    \class QmlInfo
+    \brief The QmlInfo class prints warnings messages that include the file and line number for QML types.
+
+    When QML types display warning messages, it improves tracibility if they include the
+    QML file and line number on which the particular instance was instantiated.  
+    
+    QmlInfo statements work just like regular Qt qDebug() statements.  To include the file
+    and line number, an object must be passed.  If the file and line number is not available
+    for that instance (either it was not instantiated by the QML engine or location 
+    information is disabled), "unknown location" will be used instead.
+
+    For example, 
+
+    \code
+    qmlInfo(this) << "component property is a write-once property";
+    \endcode
+
+    prints
+
+    \code
+    QML ComponentInstance (unknown location): component property is a write-once property
+    \endcode
